Pairs well with

olmocr

Open toolkit that linearizes messy PDFs — scans, tables, equations, handwriting — into clean ordered Markdown with a self-hosted vision-language model. Built for LLM training data and RAG ingestion.

Why it fitsolmocr's cleaned text is exactly what you embed and store for retrieval — feed its output into Chroma as the vector store behind a RAG app. Looser than the LlamaIndex pairing since any embedder/DB works, but Chroma is the natural open-source landing spot.

LlamaIndex

Data framework for connecting custom data sources to LLMs — ingestion, indexing, retrieval.
